I am having issues narrowing down my electrical issue. I have no power to fuse 52 the front airbag fuse. And I believe that it causing my issues. I allready changed the PDM out with a new one and i still have the same issues. Also fixed some broken wires as well. HELP, i dont know where to look next.

 

Need to know what you are driving......

 

My fault Im new i added it to my profile but it didnt to the thread, Its a 2003 dodge 2500 5.9l cummins

 

If I put power to the number 52 fuse all the lights go off. I Didnt drive it like that so im not sure on the speedo.

 

That fuse gets power from the ignition switch. Orange wire, pin 14 on the ignition switch connector, but, that portion of the switch gets ITS power from fuse 3 in the PDC, 30 amp fuse.

 

I changed the ignition, and didn't notice anything bad with the wiring going to it. I just checked fuse 3 and its good as well.

 

Are you getting power at pin 14 on the ignition switch with the key on?

 

ill have to pull it apart and double check in the morning, Ill let you know. Thanks

 

Sorry for the Long wait. Life tends to get in the way of projects. I have no power at the orange wire at the ignition switch

 

Kinda lost track of where I was going with this.... but, all your issues tie back to the speedo, find out why that isn't working, and everything else should follow. I have wiring diagrams, but, not a service manual, so I am not sure where it gets its signal from for the speedo, one of the wheel speed sensors, but, which one? If you have a scanner that can read live data, (ABS system), see if you are getting rational readings from the sensors.
